Which is better – glass or perspex?
Both will protect your print and filter some of the harmful rays of light. Glass is cheaper, but it breaks easily. Ultraviolet filtering glass and perspex are available at a higher cost. Since glass is heavier than plastic, it may be impractical for very large prints. Always use clear glass and not the non-reflective type. Perspex although lighter, is more expensive than ordinary glass, scratches easily, and carries an electrostatic charge which causes it to attract dust. With time, perspex also tends to sag in the centre, possibly touching your print.
